clamshell if you really can't squeeze 2 dbs inEDIT :steve said in his book that it's good for the box to have room to breathe. what's the mounting depth of your subs ? they need to be rather shallow to clamshell

it'a a great idea. do you plan to remove the bottom lids on both the boxes, like having a common vented chamber ?you can use only one bottom lid to save some space. cutting off 1 inch won't hurt the box by much. you can add some polyfill to repair.

I am going to build my Double 10 DB this weekend. i ended up with a design so that the ports are at the ends. I will get some pics of the box, i plan to "rhino" spray on coating for it or an equivalent.

So i finally got the box together, with much clamping and a full sheet of 3/4" MDF.......... DAAAAAAAAMN, This thing absolutely SLAMS in the back of my bug!!!! ;D (2) 10" in there with a center baffle and two adjustable inserts facing away from each other.

Here a couple pics, taped shut for testing and baffles taped in for now......

I still need to tune..... right now one is right behind the hald moon, the other covers it by 1/2". Sounds WOW! i dunno how to tune properly.........

My plan right now is to cover it with rustoleum hammertone silver paint, I am going to rubber mount isolate it from the floor of the car and put the amp underneath i think.

I am planning on a cargo area in front of the box where the seats used to be, so i might mount it concealed in there too. and for effect i want to put a couple green LED's inside the lid of the box that pulse with the sub.
